the answer is b)-7 or it could be 5
Given:
yesterday = 270
today = 216
yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.
270 - 216 = 54 * value of the change in ticket sales
54/270 = 0.20 x 100% = 20% * percent of change
There was a 20% decrease in ticket sales.
The correct answer is only A, because you need the tenths place to be greater than the number on the left, and not just the hundredths place.
P.S. Even though I'm a beginner, I took Multi-Variable calculus in 12th grade.
P.P.S. STOP PUTTING ON RANDOM ANSWERS ON QUESTIONS JUST SO YOU CAN GET THE POINTS!!!!!!
So take 4x-2x=4 first combine like terms so now u have 2x=4. now you will isolate the x to find what it equals. divide 2 from both sides so u have x=2. did this help any?
Using the tagent rule:
Tangent(angle) = Opposite Leg / Adjacent leg
Tangent(51) = x / 10
x = 10 * Tangent (51)
x = 12.349
x = 12.3 ( Rounded to the nearest tenth)
